The Barito subgroup was first proposed by Hudson (1967), comprising the three branches East Barito, West Barito, and Mahakam (Barito–Mahakam). It is thought by some to be a Sprachbund rather than a genuine clade. For example, Adelaar (2005) rejects Barito as a valid group despite accepting less traditional groups such as North Bornean and Malayo-Sumbawan.
Blust (2006) proposes that the Sama-Bajaw languages also derive from the Barito lexical region, though not from any established group, and Ethnologue has followed, calling the resulting group 'Greater Barito'.
